摘要 目的探讨老年股骨粗隆间骨折PFNA术后内固定周围再骨折的原因。方法选择行PFNA内固定术治疗的老年股骨粗隆间骨折患者,发生内固定周围再骨折患者12例为研究对象,根据文献及病案收集进行分类后尝试分型,Ⅰ型1例,Ⅱ型9例,Ⅲ型1例。结果明确老年股骨粗隆间骨折PFNA术后内固定周围再骨折的五大原因:主钉形变应力、主钉过短、隐匿性骨折、医源性骨破坏、骨质疏松。经二期手术后,患者后期回访均恢复良好。12例患者术后经3~16月,平均回访时间为6个月,患者随访1年后无感染,无异常活动和内固定无松动滑脱断裂。结论老年股骨粗隆间骨折PFNA术后内固定周围再骨折原因较多,进过分析原因予重视,可以降低周围再骨折风险。
